WHEEL.

Specification of Letters Patent.

Application filed August 11 1906.. Serial No. 330,157.

To all whom it may concern:

Be it known that I, DUNCAN ROBINSON, of Brookline, county of Norfolk,State of Massachusetts, have invented an Improvement in Wheels, of whichthe following description,

in connection with the accompanying drawings, is a specification, likecharacters on the drawings representing like parts.

This invention relates to wheels, and has I for its object to improvethe construction of the same, to the end that the felly and spokes,

- which form the outer part of the wheel, are ,yieldingly' supportedupon the hub or inner part of the wheel and are also yieldinglyconnectedwith the hub, and, furthermore, are held against lateral movement withrespect to the hub.

The inventionconsists in a wheel having a pneumatic tubular ringinterposed between the outer part of the wheel and the hub, and springs,which are arranged at opposite sides of said wheel and which areconnected at their ends to the outer part of the wheel and;

' to the hub, thereby yieldingly supporting the outer part of the wheelon thehub and also yieldingly connecting it with the hub and providingagainst lateral movement of the outer part of the wheelwith respect tothe hub.

Figure 1 shows in side elevation a wheel embodying this invention. Fig.2 is a vertical section of the wheel shown in Fig. 1, taken on thedotted line 2 2.

. detail to be referred to.

arepresents the felly, the spokes, all of usua or suitable construction,and d a' ring into which the spokes arefitted and to which they areconnected in any usual or suitable manner.

sides of the pneumatic ring a'set of springs 6 represents the hub ofthewheel, which is- .made of lesser diameter than the ring (1. A

pneumatic tubularring f is placed between the ring (1 and hub e, andsaid ring and hub are or maybe both'grooved to receive said ring andassist in holding it in place: The pneumatic tubular ring will beprovided with a valve as usual in pneumatic tires. At both are providedwhich are connected to the ring d and to the hub. As herein shown, C-springs g are employed for this purpose, as many of them being providedas desired, and they will be arranged at regular distances a art aroundthe wheel. t e springs g to the ring (1 and to the hub, a ring it issecuredto each side of. said-ring cl,

Fig. 3 is a sectionaf b'the tire thereon, c

To securely attach.

having projections h, and a ring 1', is secured to each end of the hube, having projections '6' The projections h, and i are slotted orrecessed to receive the ends of the springs g and'are provided withholes through which screws or bolts pass, which pass through holes inthe ends of thesprings; to thereby rigidly secure the ends of thesprings to the projections. Any one of the springs -g may thus bereadily removed, or, if desired, the

pairing the wheel when necessary. When the inner ends of the springs areconnected to the hub and their outer ends to the ring d,

it will be observed that both ends of each spring occupy the same radialposition with respect to the wheel. The springs thus provided not onlyserve as a yielding connection between the outer part of the wheel andits hub or inner part, but also serve to prevent 'undue lateralmovementof the outer part of rings h and i at either side of thewheelmay' be removed, thereby providing for .easily rethe wheelwithrespeot to its hubas, for inf stance, when thevehicle is turnedquickly,

the springs 9 being made quite strong to en'- able them to withstandsuch lateral strain. The springs 9 therefore act to hold the outer partof the wheel in a predetermined position with respect to its hub. Iprefer to employ G-springsfor this purpose, as they take the strain in ayielding mannerin all the different positions they are caused to occupywhen traveling around with the wheel. 1

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. wheel comprising a felly, spokes andring at connected together, a hubof lesser diameter than the ring (1, a pneumatic ring interposed betweenthe ring (1 andthe hub. and springs at opposite sides of the wheelconnected at their outer ends to said ring (1 and.

at their inner ends to said hub, both ends of each spring occupying thesame radial posiwheel, substantially -both ends of each spring occupyingthe same radial "position with respect to the wheel,

substantially as described.

' 3. A Wheel comprising afelly, spokes and ring d connected together, ahub cf'le'sser di:

ameter than the ring d, a pneumatic-ring interposed between saidring dand the hub, a

plurality of C-springs at both sides 'of'the wheel,,'supports attachedto'the ring d to which the outer ends of said springs are a t tached andsupports "attached" to the hub to which the innerendsoi said springs.are attached, substantially as" described;

"'4. A Wheel comprising a felly, spokes and ring'dconnected together; ahub of lesser di' ameter than the ring d, a' pneumaticring interposedbetween said ring (I and the hub, a

plurality of Q-springs at both sides of the Wheel, laterally-extendedsupports on the ring d to Which the outer ends of said springs areattached and supports on the hub'to which the inner; ends of saidsprings are at? set otsprings at each side of the wheel, rings attachedt'o'the opposite sides o'f the'ringr d to which the'inner ends of saidsprings are at tached and rings attached to the opposite ends of the hubto which the outer ends ofsaid. Springs are attached, s b ta tidescribed. v v v i 6. A Wheel'comprising a telly, spokes and ring (1connected together, a hub of lesser diameter than the ring d,- apneumatic ring interposed between said ring (1 and the hub a set offQ-springs at each side of the Wheel,

rings attached to the opposite sides ofthe ring d having projectionstowhich one of the ends of said springs are attached, and rings attachedto the opposite ends of the hub,

having projections to WhlChllle other ends of said springs are.attached,substantially as.

described.
